Based on the hybrid hypersingular integral equation-lattice Boltzmann methods (HHIE-LBM), the porosity and permeability evolution and evaluation process in anisotropic saturated porosity multiscale-multiphase-multicomponent (ASP-MS-MP-MC) structures under ultra high temperature and pressure conditions was analyzed on parallel CPU and GPU platforms. First, virtual physical models at multi-spatial scales (2 µm, 5 µm and 10 µm) were restructured by computerized microtomography technology and data. Second, using HHIE-LBM methods, the anisotropic porosity and permeability tensor at core level and pore level under ultra high temperature and pressure conditions were calculated. Third, the evolution and evaluation process of the porosity and permeability as a function of multi temporal spatial scales was investigated. Finally, the relationship between porosity and permeability and ASP-MS-MP-MC structures (micro-meso-macro-scale) was explored.porosity and permeability tensor, anisotropic saturated porosity multiscale-multiphase-multicomponent structures, hypersingular integral equation method, lattice Boltzmann method, ultra temperature and pressure, parallel CPU and GPU Citation: Zhu B J, Cheng H H, Qiao Y C, et al.

Chin Sci Bull, 2012Bull, , 57: 320327, doi: 10.1007 In the past 10 years, with developments in geophysics, seismology, mechanics and materials, the anisotropic saturated porosity multiscale-multiphase-multicomponent (ASP-MS-MP-MC) structures have attracted the attention of researchers for its wide application in these interdisciplinary fields. However, many micro-meso-macro mechanisms have not yet been clearly evaluated, especially with regard to their structural physical characteristics. To investigate the porous physical character and structure problem, Berger [1] explored fabric tensors of anisotropic porous solids using boundary elements and the Green's function method. Roberts and Garboczi [2] studied elastic properties of porous ceramics using a finite element method, and established the relationship between pore shape and structure. Almqvist et al. [3,4] used measured seismic velocities to analyze the elastic properties of anisotropic synthetic aggregates, containing mixtures of calcite and muscovite, under uniaxial loads ranging from 20 MPa up to 400 MPa. Zhang [5,6] presented the physical mechanism of fully and partially saturated geomaterials, and obtained significant results for the complex coupled fluid-solid system. Wei [7] provided the governing equation of static and dynamic behavior of multiphase porous media. Diabiraa et al.[8] discussed the porosity and permeability evolution accompanying hot fluid injection into the diatomite problem. Mark [9] explored permeability in fibrous porous mediausing the
